Description
Technical Field
The invention relates to the technical field of rubber products, in particular to a rubber wire outer sheath for an outdoor electrical appliance and a preparation method thereof.
Background
The rubber material cable material that the electric apparatus that uses in the open air in the existing market used is mainly chlorinated polyethylene basically, but general chlorinated polyethylene's low temperature resistant performance is relatively poor, and cable compliance is low when some low temperature areas (40 ℃ below zero) outdoor use, and the cable is stiff, and the user uses inconveniently, experiences and feels poor. And after the cable is used in a low-temperature environment for a long time, the phenomena of cable skin explosion, crack and the like occur.
The rubber cables which can meet the low temperature resistant requirement in the current market are mainly made of Ethylene Propylene Diene Monomer (EPDM) which is high in price and high in product cost. Therefore, a rubber material which can meet the low temperature resistance requirement and reduce the cost on the basis of meeting various performances required by the outer sheath material is researched to become one of hot spots in the rubber material market.
The traditional rubber wire production mode is mostly high-temperature steam vulcanization, and a small part of the traditional rubber wire production mode also adopts an electron irradiation process. The former needs to be fired, which pollutes the environment, and has large energy consumption and high production cost. The equipment investment cost of the latter is high, and at present, only a few cable enterprises in China have.
